Not to diss Gronk (that would be stupid, he is gigantic!), but it's a lot easier to get endorsement deals when you are white, love to be on camera, and are not determinedly "ghetto" in your public persona. Gronk reps Dunkin Donuts, BodyArmor, and Nike. Marshawn didn't even get an endorsement for Skittles until 2014!!! He is the king of endorsements now, but he truly did it "his way".
